5.2 & Follow-up (Making Tables on a Calculator)

Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns.
INV 1 Essential Question: What are some of the variables around us?

Notes:


Problem 5.2
A1Q. Use your calculator to make a table for the equation y=3x.
I did this on the calculator.

2Q. Copy part of the calculator's table onto a paper.

X	Y
0	0
1	3
2	6
3	9
4	12
5	15
6	18

3Q. Use your table to find x=5.
X=5, Y=15
B1Q. Use your calculator to make a table for the equation y=5x+2.
I did this on the calculator.
2Q. Copy part of the calculater's table onto a paper.

X	Y
0	2
1	2.5
2	3
3	3.5
4	4
5	4.5
6	5

3Q. Use your table to find y=5x+2.
X=5, Y=4.5

Follow-Up
1. Use your calculator to make a graph for the equation y=3x.
Y is incresing as X is the slant is going upwards and is strait.
2. Use your calculator to make a graph for the equation y=0.5+2. Describe the graph.
Y is constant while X is increasing. the slant is going across. It is in a strait line.
3. How do the graph for question 1 and 2 compare?
Their similaraties are that the data is in a strait line and both the X variables are increasing.
4. How would you make a graph for equation y=3x and y=0.5x+2 without a graphing calculator?
I could use the equation to find the data and plot a graph.
